Unfortunately, the problem is (with two out of three) that you asked the wrong questions. When Clinton says that he talked to several people that fall he means that it was fall (the season between summer and winter) when he talked to those people.
I will need more context to determine what is meant by "I got waxed" means in the sentence you quote.
When he says "as would so often happen in the years ahead, I turned to Hillary for judgment and advice" he means that he often turned to Hillary for advice ("in the years ahead").
Does that help?
